. ful Improvements in Type-Writing Ma'- chines, of which the following is a speci fication.

My invention relates to typewriting machines and more particularly to. means for readily squaring work sheets and directing themproperly to the platen, and the object of the invention, generally stated, is to provide simple and efficient means of the char- 1 ticularly pointed out in the appended claims.

acter specified.

To the above and other ends which will hereinafter appear, my-invention consists in the features of construction, combinations of devices and arrangements of parts set forth in the following specification and par- In the accompanying drawing in which likereference numerals designate corresponding parts in the different views, Figure 1 is a fragmentary, vertical, fore and aft sectional view, showing theup per portion of a typewriting machine embodying my invention. Fig. 2 is a front elevation 30" of a. paper table made in accordance with my'invention; the-brackets by which the table is secured being shown in section.

I have illustrated my invention in the present instance embodied in a Monarch ma- Qchine, only so much of said machine being shown as may be necessary to arrive at an understanding of the invention in its embodiment therein. It should be understood,

however, that the invention may be embodied in various, styles of typewriting ma; chines.

The frame of -the machine comprises corner posts 1 and a" top plate 2. Brackets 3 are fixed to the top plate and have oppoa.

sitely grooved guide-rails 4 secured thereto by. screws 5. These grooved guide rails.re--

ceive anti-friction balls or rollers 6 which are likewise received in oppositely grooved faces era guide bar-7, The guide bar constitutes the rear cross bar of the carriage from which forwardly projecting and bars 8 extend. These end bars are provided with hearings to receive a platen shaft 9 on which a cylindrical platen 10 is mounted. The usual cotiperative paper feed devices are employed, the main paper feed rollers 11 and auxiliary paper feed rollers 12 alone being diagrammatically shown. These feed rollers project'through apertures in a paper apron 13 mounted in the usual manner to receive a work sheet in the rear of the platen. The paper table is supported on forwardly extending bracket arms 14 which project from the guide bar 7. These bracket arms are provided with the usual headed screws 15 received at theirthreaded ends in tapped openings in the brackets 21 d by means of which the usual paper tab e is detachably connected to the carriage in the Monarch machine.

In accordance with my present invention 1 have provided a detachable paper table,

chute or guide, which may be readily substituted for the ordinary paper table employedv in the machine. -This substitute paper table is indicated as a whole bythe reference numeral 16 and comprises bracket arms 17 slotted at 18 to straddle the stems of the screws 15; WVhen the screws 15 are tightened the paper table is secured in place. By loosening the screws the paper table may be readily detached and the ordinary paper table substituted therefor. The brackets 17 are secured to a supporting plate 19 fixed to the rear of the paper table. The rear wall 20 of the chute-like or trough-like paper table constitutes a support for the .work sheets and extends throughout, or substantially throughout, thelength of the platen and is so disposed that work sheets a and b resting thereon are directed to the bight between the main paper feed rollers and the platen, as represented in Fig. 1. The forward or front wall 21 0f the chute or trough has its lower portion parallel with the rear wall 20, whereas theupper portion of the wall 21 is deflected forwardly-as indicated in Fig. 1, and terminates at 22 at about twothirds the height of the reariwa-ll 20.. The chute is provided with end walls gwhich close the ends of the chute. These end walls are preferably formeilby blocks 23 and 24 .which are interposed between the'front and rear wallsof thetchut iind are connected thereto by rivets 25.

'tion .of. each block has asubstantially .vertically disposed inner wall 26, whereas theupper portion of each block has an outwardly inclined contact face or wall'27. A third spacing block28 isintiarposdlbetween the front and rear walls of the chute inter- The lower end porp 28 being in the. nature of a fore and aft partition which divides the chute into two separate compartments arranged end .to end and each inclosed on four sides. The spacing block 28 is secured to the frontand rear walls by rivets 29 and has parallel walls or contact faces 30 at the lower end portion thereof, whereas the opposite sides of the upperend portion of the partition are in.- clined toward each other, as indicated at 31;

F rom the foregoing description it will beunderstood that each of the end walls 26 and the companion parallel wall 30 constitute side edge guides which are cooperative with the side edges a and b of the work sheets a and b respectively, as illustrated in Fig. 2. The two compartments of the chute, divided by the partition 28, are of different widths; that is, considered in the direction of the length of theplaten. The construction is intend id more particularly as a card guide,

and although the cards or work sheets a and b have been referred to as two separate sheets, the construction is intended .more

particularly for squaring and properly guiding a card geithcr lengthwise or widthwis'e, as desired. It, for instance, the line a in Fig; 2 be taken to indicate the length of the card and the lined be taken to indicate the vi'idth of the card, then the card will be di. cted, lengthwise and properly squared and directed if inserted in the compartment B. i If, on the other hand, the card be turned at right angles, so as to feed it widthwise instead of lengthwise, then it may be inserted in the compartment A and the distance between the walls 26 and 30 in said compartment' correspond substantially to the line a, or to the length ofthe card, so that it will be properly guided anddirected widthwise in its feed through the machine. The inclined walls 27 and 31 in each compartment guide the cards properly and effectively to a position where the side edges of the cards, whethe'rjthey are fed lengthwise or widthwise, will co-act with the parallel portions 26 and 30 of the end walls and partition wall respectively, which constitute side edge guides for properly squaring the work sheets or cards as they are introduced into themachine and accurately presenting the leading edges thereof to the feed rollers 11 parallel with the printing line.

effective means for squaring and It will be observed that each of the compartments A and B is free from obstruction so that a work sheet introduced into either.

of the compartments is prqperly squaredas' fee I it passes directly to the rollersll.

understood that I have provided simple and guiding cards either lengthwise or 'widthwise and for directing them properly'to the platen in the rear thereof, and t at the cards may be quickly and effectively handled with the aid of my construction without thenecessity of exercising precaution and judgment on the part. of theoperator in introducing the cards into the machine.

Various changes may be made without departing from the spirit and scope of my invention.

What I claim as new and desire to secure by Letters Patent, is
